i do not know. that is why i am asking you on answers.com. thank you . goodbyee

The endocrine organs you would expect to be relatively larger in humans than cats include the thymus and the adrenal glands. Adrenal glands are also known as suprarenal glands.
The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. In humans, the major endocrine glands are the thyroid gland and the adrenal glands.
Endocrine glands in humans are the hypothalamus, pituitary (anterior and posterior , gonads (testes/ovaries), placenta (when a female is pregnant), alimentary system (digestive tract and associated organs), thyroid, and adrenal glands.
Humans have paired salivary glands.
In humans, apocrine and merocrine sweat glands form the primary method of cooling.

The parathyroid glands are small endocrine glands in the neck that produce parathyroid hormone. Humans have four parathyroid glands, which are usually located behind the thyroid gland. Parathyroid glands control the amount of calcium in the blood and within the bones. The parathyroid gland also regulates the metabolism of both calcium and phosphorus.
Earth system is a self regulatory system that comprise of physical, biological, chemical, and human systems within it. The earth system that includes humans is called biosphere.
Namely, the heart and lungs! The great vessels of the heart, the respiratory, oesophagus and some endocrine glands. Plus a few other major things.
The structure in humans that the digestive glands are comparable with crayfish are the glands that are found in the mouth and the stomach. These glands will secrete salivary amylase and HCI respectively to aid digestion in humans.
In physiology, the endocrine system is a system of glands, each of which secretes a type of hormone directly into the bloodstream to regulate the body. The endocrine system is in contrast to exocrine system, which secretes its chemicals using ducts. It derives from the Greek words endo (Greek ένδο) meaning inside, within, and crinis (Greek κρινής) for secrete. The endocrine system is an information signal system like the nervous system, yet its effects and mechanism are classifiably different. The endocrine systems effects are slow to initiate, and prolonged in their response, lasting for hours to weeks. The nervous system sends information very quickly, and responses are generally short lived. Hormones are substances (chemical mediators) released from endocrine tissue into the bloodstream where they travel to target tissue and generate a response. Hormones regulate various human functions, including Metabolism, growth and development, tissue function, and mood. The field of study dealing with the endocrine system and its disorders is endocrinology, a branch of internal medicine.Features of endocrine glands are, in general, their ductless nature, their vascularity, and usually the presence of intracellular vacuoles or granules storing their hormones. In contrast, exocrine glands, such as salivary glands, sweat glands, and glands within the gastrointestinal tract, tend to be much less vascular and have ducts or a hollow lumen.In addition to the specialised endocrine organs mentioned above, many other organs that are part of other body systems, such as the kidney, liver, heart and gonads, have secondary endocrine functions. For example the kidney secretes endocrine hormones such as erythropoietin and renin.The endocrine system is made up of a series of glands that produce chemicals called hormones. A number of glands that signal each other in sequence is usually referred to as an axis, for example, the hypothalamic-pituitary-adrenal axis.
Cats do not have sweat glands unlike humans.
There are animals who have "poo glands", humans don't.
Humans have paired salivary glands.
